項記載のパイプ溝付は装置。(1) It includes a lower mold, an upper mold, a complete mold clamping means, and an inner mold that supports the vibrator to be processed from inside, and these are assembled into the lower mold and the upper mold. A lower semicircular die surface and an upper semicircular die surface are respectively provided, which form a circular hole with an inner diameter equal to the outer diameter of the vibrator to be processed when the vibrator is machined. The inner mold has a cylindrical outer circumferential surface, and the outer circumferential surface corresponds to the protrusions of the upper and lower molds when the inner mold is inserted into the upper and lower molds. A pipe grooving device characterized in that an annular groove is provided at a position, and the outer diameter of the circumferential surface is divided into a plurality of parts along the axial direction so as to be expandable and retractable.・(
2) Utility model registration claim 1, in which the inner mold is provided with a stepped contact surface that regulates the position of the end surface of the vibrator to be processed.
The pipe groove described in the section is a device.
